Principal Ann Esselstein, who is battling cancer, also spoke at the event and received a surprise call from her idol, Duke University men's basketball head coach Mike Krzyzewski. She said Coach K was empathetic about her situation and complimented her leadership qualities. Participants raised funds for the American Cancer Society. Esselstein said a total amount isn't known but could surpass $20,000 for the first time in the event's 14 years.
